FLUXING AND CLEANING APPARATS.

Application filed January 28, 1922. Serial No. 532,484.

This invention relates to a fluxing and cleaning apparatus for use withmetal coating machines, such as are-employed for preparing sheet metalband or ribbon stock of copper or brass in the manufacture of automobileand other radiator tubes. p

The main object of my invention is to provide a novel apparatus by whichthe metal stock may be continuously cleaned and fluXed as it passesthrough the 'apparatus on its way to the metal coating and chillingdevices of the entire machine, and thus permit thev rapid making of thetubes by a continuous and` uninterrupted process.

The invention consists further in the matters hereinafter described andclaimed.

In the accompanying drawings z- Fig. 1 is a verticallongitudinal.sectionalview throughjthe apparatus ofmy invention.

Fig. 2 is a top plan view of the Same, and

Figs. 3 and 4-are vertical sectional views taken on lines 3-3 and 4,4,respectively, of Fig. 1. l

As shown in the drawings, the sheet metal band or ribbon 4 is su pliedto lhe apparatus 1 in coil or roll fldrm- 5 which is supported by anupright bracket Gat the entrance end of thefdevice.

The apparatus 1 has an upwardly opening tank 7 supported abo-ve the-Hooror other underlying surface by a bench like frame, comprising horizontalside members 8, 8 and vertlcal end members or legs 9, 9. Fixed in thetank 7 is a block 10. This extends lengthwise of the tank and has itssides short of the side walls of the tank, as shown in Fig. 3. Saidblock 10 is provided between its ends with a de ression or concaverecess 11, and the upper ace of the block including this recess is shodor covered with a layer' of fabric 12, as shown.

Arranged above the fixed block 10 is a movable block 13. This has adepending rounded portion14, curved complementary to the recess 11 anddesigned to substantially t in'the same. Said curved portion 14 has itslower face shod or lined with a layer of fabric 15 which also followsthe contour of the fabric 12 beyond the curved portion 14 and there isbent upward and secured about a cleat 16 carried by said block 13, asshown.

Said blockv 13 is raised vertically above and away from the block 10 bya vertical rod 17 extending upward above the tank 7 at kone side of thesame and guided by a strap 18 fixed to thel machine, as shown in Figs. 2and 3. The upper end of said rod 17 is curved inward over the tank 7 anddownward to a fiat horizontal bar 19. This is secured to the block 13and extends beyond the same, as shown in Figs. 1 and 2. The rod 17 ismoved upward to separate the blocks 10 and 13 by a depressible footpedal 2O below the machine, `as shown. When the block 13 is raised outof the tank 7, the blocks 10 and 13 are separated and themetal band orribbon 4-from the roll 5 may be action to which the band is subjectedre` moves all grease and verdigris therefrom and all foreign substancedeposited thereon and insures a thorough fluxing and cleaning of t-heribbon, preparatory to coating with metal.

-On leaving the block 13, the metal ribbon or band 4 passes over afabric pad or wiper 21 on the lower `block 10. From this, Ithe ribbon-enages aplurality of fabric pads or wipers 22,g23, 24, and 25, al1arranged in the tank 7 beyond the blocks orpads 10 and 13 in thedirectionl of' travel of the metal band or ribbon 4. The second pad 23is arranged between the first and third ones 22 and 24, and thelast pad25 is beyond the third, as shown in Fig. l1. The first and third ads 22and 24' are carried by the bar 19 an en- 'gage the upper surface of themetal band and are secured to and between cross bars 26.

on the tank 7, as shown in Fig. 2. .These pads or wipers 22 to 25 areabove the level of the liquid or solution in the tank 7 and,

, not only remove the surplus lux, but all foreign substance andsediment gathered, and assure a thorough and positive distribution ofthe flux through the wiping motion` formed by the travel of the ribbon4. To guide the ribbon 4 into engagement with said pads 22 to 25, thereare laterally spaced guide rods 27, 27 carried by and depending fromsaid bar 19 in advance of the pad 22 as shown in Figs. 1 and 4. Onentering and leaving the tank 7, the ribbon 4 passes over rollers at the`ends of the same, as shown.

/The feed on the ribbon 4 in the tube mill (not shown) with which thefluxing and apparatus 1 is employed, draws the ribbon bet tween theblocks and across the Wipers in the apparatus 1 in accordance with thefeed in the mill. From the apparatus 1, the ribbon passes through themetal coating apparatus which coats one or both sides ofthe ribbon withmolten metal, such as solder, as

" required. The metal coating apparatus `is disclosed and claimed in mypatentv No. 1,608,855, granted Nov. 30, 1926. From the coating devicethe ribbon 4 passes through a chilling apparatus (not shown) to hardenthe coated ribbonjust prior to entry into the 1. A flux applyingmachine, comprising atank adapted to contain a f luxing solution, twoblocks arranged one above the other, one

y of, said blocks being fixed in said tank and submerged in the solutiontherein, the other block being movable toward and from said {ixed block,said blocks having fabric 1in- .surfaces to engage and clean both siings on their opposed surfaces to engage and 'clean both side's'of thesheet metal band or ribbon drawn between them, and u right wipers' abovethe solution in said tan and across which the band passes after leavingsaid blocks.

wardly opening concave recess between itsl ends, said movable blockhaving a depending rounded portion to fit in said recess, sai blockshaving fabric linings on their opiposed e's'of the lsheet metal band orribbon drawn between them, 4and wipers above the liquid in said tank andacross which the band passes after leaving said blocks.

3. A flux applying machine, comprising a tankadap'ted to contain afluxing solution, two blocks arranged one above the other, one of saidblocks being fixed in said tank and submerged in the solution therein,the other block being movable `toward and from said iixed block, saidblocks having fabriclinings on their opposed surfaces to engage landclean both sides of the sheet metal band or ribbon drawn between them,and 4wipers above the solution in `said tank and across` which the bandpasses after leaving said blocks, certain of said wipers being carriedby said movable block and others fixed in said tank.

JOSEPH D. HARRIS.
